Bayard Delafield Clarkson Sr. (born July 15, 1926) is an American physician, hematologist, and oncologist.
Clarkson was born in New York City on July 15, 1926. He is the son of the wealthy banker, Robert Livingston Clarkson Sr. (1892–1969), who was the president of Chase National Bank from 1928 to 1929. R. L. Clarkson Sr. and his wife Cora G. Clarkson née Shields (1897–1981) had two other sons, Robert Livingston Clarkson Jr. (1924–1965) and Peter Schuyler Clarkson (1930–1950). The Clarkson family is related to Matthew Clarkson (1758–1825) and is connected to Clark University. [1] [2] When the attack on Pearl Harbor occurred, Bayard Clarkson was attending New Hampshire's St. Paul's School. In December 1943 he enlisted in the U.S. Navy's aviation program. However, he was diagnosed with inactive tuberculosis and judged ineligible for active duty. Thereupon, he joined the American Field Service (AFS). In the summer of 1944, AFS sent him orders for two weeks of basic training, after which he was sent overseas in August 1944. From early September 1944 through March 1945 he served in Italy with Unit CM 90 of the AFS. In the spring of 1945 he volunteered for service in the evacuation of Bergen-Belsen concentration camp. In July 1945, he shipped out from Copenhagen. In autumn 1945 he matriculated at Yale University. [1]
After graduating from Yale, Clarkson studied medicine at the Columbia University College of Physicians and Surgeons, where he graduated with an M.D. in 1952. At New York Hospital (now called Weill Cornell Medical Center), he served his medical internship and residency [3] in endocrinology and hematology. [4] In 1958 he became a Special Lasker Fellow in Clinical Chemotherapy at (what became in 1960) the Memorial Sloan Kettering Cancer Center (MSKCC), where he continued working and coauthoring articles [5] until 2017. [6] AT MSKCC he became in 1970 the Chief of the Hematology Service and in 1980 the Enid A. Haupt Chair of Therapeutic Research. He was from 1975 to 1989 the MSKCC's Chief of the Hematology/Lymphoma Service. [5]
At the beginning of his career of MSKCC he worked with three outstanding chemotherapy pioneers, David Karnofsky, Cornelius Rhoads, and Joseph Burchenal. Clarkson and his colleagues were among the first to develop effective therapies for adults with acute leukemias and lymphomas. [3] [7] Much of his work focused on the search for selectively targetable differences between normal cells and abnormal stem cells that are quiescent (but potentially proliferative) in CML (Chronic Myelogenous Leukemia). [8] He is a leading expert on the "intracellular signaling pathways that are altered by the BCR/ABL fusion genes". [3]
From 1968 to 1992, Clarkson was a trustee of Cold Spring Harbor Laboratory. [5] From 1973 to 1974 he was the president of the American Society of Clinical Oncology (ASCO). [3] From 1980 to 1981 he was the president of the American Association for Cancer Research (AACR). [5]
In 1946 in Keene, New Hampshire he married Virginia Lomax Clark (1926–2019). They had three daughters and one son. [9] [10]
Acute lymphoblastic leukemia (ALL) is a cancer of the lymphoid line of blood cells characterized by the development of large numbers of immature lymphocytes. Symptoms may include feeling tired, pale skin color, fever, easy bleeding or bruising, enlarged lymph nodes, or bone pain. As an acute leukemia, ALL progresses rapidly and is typically fatal within weeks or months if left untreated.
John Edgar Dick is Canada Research Chair in Stem Cell Biology, Senior Scientist at the Princess Margaret Cancer Centre, University Health Network and Professor in the Department of Molecular Genetics at the University of Toronto in Canada. Dick is credited with first identifying cancer stem cells in certain types of human leukemia. His revolutionary findings highlighted the importance of understanding that not all cancer cells are the same and thus spawned a new direction in cancer research. Dick is also known for his demonstration of a blood stem cell's ability to replenish the blood system of a mouse, his development of a technique to enable an immune-deficient mouse to carry and produce human blood, and his creation of the world's first mouse with human leukemia.
Charles L. Sawyers is a Howard Hughes Medical Institute (HHMI) investigator who holds the Marie-Josée and Henry R. Kravis Chair of the Human Oncology and Pathogenesis Program (HOPP) at Memorial Sloan Kettering Cancer Center (MSK). HOPP is a program created in 2006 that comprises researchers from many disciplines to bridge clinical and laboratory discoveries.
Brian J. Druker, M.D. is a physician-scientist at Oregon Health & Science University (OHSU), in Portland, Oregon. He is the chief executive officer of OHSU's Knight Cancer Institute, JELD-WEN Chair of Leukemia Research, Associate Dean for Oncology in the OHSU School of Medicine, and professor of medicine.
Clara Derber Bloomfield, was an American physician and cancer researcher. Her work focused on the genetic changes that are present in certain types of blood cancers, and how those can be utilized to improve treatment for the affected patients.

Carcinocythemia, also known as carcinoma cell leukemia, is a condition in which cells from malignant tumours of non-hematopoietic origin are visible on the peripheral blood smear. It is an extremely rare condition, with 33 cases identified in the literature from 1960 to 2018. Carcinocythemia typically occurs secondary to infiltration of the bone marrow by metastatic cancer and carries a very poor prognosis.

June Biedler was an American scientist primarily known for her discovery of proteins that lead to resistance of cancer cells to chemotherapy. Her work has been crucial for an understanding of both the development of drug resistance and also for strategies to circumvent such resistance. In addition, Biedler made important contributions to an understanding of the molecular mechanisms of neuroblastoma development, particularly of the role of the N-myc oncogene in the genesis of neuroblastoma
